fIEELING-MACHINE.

Application filed December 4, 1908. Serial No. 468,022.

To all whom it may concern:

Be it known that I, JOHN E. G'LTDDEN, a citizen of the United States, residing, at Beverly, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Heeling-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to heeling machines and more particularly to machines for attaching rubber top lifts or heels t0 boots and shoes.

Where rubber top lifts or heels are attached to boots or shoes by nails or similar fastenings it is essential that the heads of the fastenings be embedded in the material of the top lift or heel a considerable distance below the tread surface thereof. When a rubber top lift is to be attached to a leather heel by nails, the nails should be so driven as to penetrate the top lift and heel, their points being clenched in the sole of the shoe and their heads buried in the top lift for a distance equal to substantially one half the thickness thereof. To secure these results in the most effective manner'I provide a separate driver for-each fastening to be driven, these drivers being mounted for reciprocation in suitable guideways, and

being given positive nail driving movements the extent of which is just sufficient to embed the heads of the nails the proper distance in the top lift; As illustrated herein, these drivers are in the form of plungers and are arranged to play in passages formed in the nail block head of a heel nailing machine of the type shown in United States Letters Patent No. 884,513, dated April 14:, 1908, in which machine this invention is shown as embodied. In the machine shown and described in said patent, the nail block head and driver head are mounted upon a die-bed spindle, which is reciprocated by suitable mechanism to cause the nail block to force the heel against the shoe, and, subsequently, through yielding connections betw en the nail block head and driver head,

to move the driver head upwardly a farther distance, independently of the nail block head, whereby the drivers rise in theholes of the nail block and act upon the nails to force them through the heel and into the sole of'the shoe. In said machine the heel and top lift holder is pivotally mounted above the nail block, and is locked in position with the heel over the nail holes therein during the heel attaching operation, but is unlocked upon the-descent of the nail block after the heel is attached, to permit the heel holder to heymoved automatically out of position, and the top lift holder into position over the nail block, whereby, upon the second rise of the nail block a top lift in said holder will be spanked upon the ends of the nails projecting from said heel. As hereinbefore stated, the plungers'which. are to act as drivers for the-top lift fastenings, under this invention, are arranged to play in passages formed in the nail block, and as herein shown these plungers have their naildriving heads positioned to lie normally flush with the upper surface of said block, and are at their opposite ends provided with yielding means applied thereto in such man-' ner as to cause said ends to normally pro ject a suitable distance below the'lower surface of said block.

The driver head, carrying the usual drivers for th'e'heel attaching nails, is preferably provided with suitable devices which are arranged to be projected to prevent said head from approaching the nail block sufficiently close to come in contact with the ends of the top lift attaching plungers upon the first, or heel attaching, actuation of. the driver head, but are withdrawn to permit a nearer approachof the driver head thereto upon its second actuation. As herein illustrated, said devices'comprise spaced, sliding stops, of wedge form, having thereon inclined ribs to enter and move within similar grooves in the driver head. These stops may be operatively connected with the heel and top lift carrier in such manner that when said carrier is movedto'loc'ate a heel over the nail block, the stops are projected, but when the said carrier moves to locate a, top lift over the nail lolock, the stops are withdrawn. This arrangement of top lift] drivers and their operating machanism in connection with a heel nailing machine of this type, whereby said drivers are rendered inoperative during the heel attaching operation, but are rendered operative during the top lift attaching operation, I regard as an important feature of my invention.

The top lift attaching drivers, as before Patented Nov. 24, 1914.

stated, are shown as being slidably mounted in the nail block, and the number and arrangement of said drivers will be determined by the number and location of fastenin s desired for the top lifts. Such top lift drivers may be, and preferably are, arranged in suitable proximity to the heel nail drivers, and under one form of my invention some, or all, of the heel nail drivers may be conveniently arranged for movement within passages which extend through the top lift drivers; but my invention is not to be considered as limited to this arrangement.

Other important features, including details of construction and combinations of parts, will be more fully hereinafter set forth and claimed.

Like reference characters denote like parts throughout the several views of the drawings.

Figure 1 is a perspective view of the principal parts of a heel nailing machine, having this invention applied thereto. Fig. 2 is a detail view, enlarged, showing the driver head and the movable stops for said head, in plan. Fig. 3 is a vertical sectional view through the driver head and nail block with a shoe thereon, on the line st l, Fig. 2, the parts being shown in the position they occupy during the heel attaching operation; Fig. 4: is a similar view showing the parts in the position they occupy during the top lift attaching operation. Fig. 5 is a perspective view of a leather heel with a rubber top lift attached thereto, showing in a vertical section through the several layers the arrange ment of the fastenings as applied by this invention.

Referring to Fig. 1, the frame 1, carries the usual shoe supportingjack 2, which is .rnounted for movements into and out of position over the nail block 3. The nail block is carried by the nail block head 4:, which has the depending rods 6, properly spaced apart and serving to guide the driver head in its movements. The driver head 7 has the grooved collars 5 securely fastened thereto by the caps 6 bolted to the driver hea d, as shown, these collars serving as sliding bearings to permit the movements of the driver head on the rods, and being, furthermore, provided with dependent guides 13 to sustain strong springs 14:, to constitute a yielding means for holding the nail block and driver head normally spaced apart. The driver head 7 has the usual supporting spindle, the same being raised and lowered by toggles actuated through a link, or other connection, from the main drive shaft, these parts being under the control of a clutch, or equivalent device, which. is preferably so constructed as to permit the nail block and driver head to be raised and lowered twice for every actuation of the clutch control lever, said parts not being shown herein but being shown and described in the patent above referred to.

The heel. and top lift carrier 8 is preferably of substantially the same construction as that shown in the Letters Patent hereinbefore referred to, except that the supporting plate for the usual heel and top lift holding gages is not extended beneath the top lift gages to form a spanker, as such e 1tension would interfere with the-operation of the plungers 15 in driving fastenings through the top lift and heel. As disclosed in said Letters Patent, the carrier 8 is provided with the heel holding gages 8, 8 and the top lift holding gages 9, 9 and said carrier is pivotallymounted for movement over the nail block and has attached thereto suitable means, as the spring-actuated link 10, which acts with a normal tendency to oscillate the carrier in a direction to locate a top lift in the carrier in position over the nail block, the carrier being caused to move in the opposite direction to locate a heel therein over the nail block by the actuator 11 carried by the nail transferrer 12.

The parts so far described are all substantially shown and described in the aforesaid Letters Patent, and form no part of the present invention.

The top lift fastening drivers are herein shown in the form of plungers 15, each having at one end thereof the head 16, and at its opposite end a washer 18, or other equivalent means to sustain the pressure of a spiral spring 17. The plungers play in passages in the nail block, said passages being enlarged to form recesses at their upper GK- tremities to receive the heads 16, and being recessed at their opposite extremities to accommodate the springs 17, said springs being normally held compressed between the shoulders formed by the ends of the recesses, and the washers The plungers are longer than the thickness of the nail block, and are normally held by the springs with their heads 16 within the upper recesses and their extremities flush with the upper surface of the block, while their opposite ends project a slight distance beyond the lower surface of the block, as shown in Fig. 3. As shown in dotted lines in Figs. 3 and fl of the drawings, the plungers may be longitudinally bored. to receive the usual heel nail drivers 7, some of which. drivers I have shown as telescopically mounted in the plungers; but while I prefer this arrangement, my invention contemplates the employment of any other form of plunger.

The stops 19 are, as here shown, of wedge form, and each has an upper edge lying normally in a horizontal plane, and a lower edge inclined thereto, the latter preferably being provided with a guiding rib 19.

As shown in Fig. 1., the driver head 7 has formed therein two guideways or grooves located, respectively, upon opposite sides of the drivers 7, and these grooves are inclined to correspond with the inclination of the ribs 19, which slide therein. A bracket 20 is shown as clamped to the stops at their rear ends by winged nuts 21, which engage threaded extensions on the stops, the extensions passing through slots in said bracket, as shown in Fig. 2, whereby to permit adjustments to accommodate variations in the lateral spacing of the stops. The bracket is, furthermore, provided with an arm 22 having a slot therein to be engaged by a crank 23, mounted on a rod 24, said rod being operatively connected to the heel and top lift holder 8, so as to turn therewith. The crank 23, as shown, is elongated in the direction of the aXis of the crank shaft whereby the bracket 22 may slide along the crank as the driver head reciprocates and is thus maintained in operative engagement with the crank in all positions of said head.

The machine is ready for operation when all of the parts occupy the positions shown in Figs. 1, 2 and 3 of the drawings, that is, after the transferrer 12 has, through the actuator 11, moved the heel holder to heel attaching position, and has deposited the requisite number of nails in the nail passages of the nail block, and a heel blank has been placed in the heel holder, and a rubber top lift loaded with nails has been placed in the top lift holder. The crank 23, bracket 20 and stops 19 are now as shown in full lines in Fig. 2, the stops being projected to lie with their upper edges in a plane above the plane of the upper surface of the driver head. The clutch controlling lever being actuated, the nail block and driver head rise, and the heel is first forced against the shoe on the jack by the pressure imparted thereto from the nail block, the springs 14 being thereafter compressed, whereby the driver head approaches the nail blockand the drivers 7 act to drive the nails through the heel and into the sole of the shoe. ()wing to the position of the stops 19, at this time, however, the driver head is not permitted to approach the nail block sufiiciently to come in contact with and actuate the plungers 15. The nail block then descends, thereby actuating the trip device to release the heel and top lift carrier, and permit the spring-actuated link 10 to move the top lift carrier into position over the nail block, this movement also serving to turn the rod 21 and thereby the crank 23, and to shift the stops 19 to the position shown in dotted lines in Fig. 2 and in full lines in Fig. l, with their edges lying flush with'the upper surface of the driver head. The nail block and driver head then rise for the second time, and the top lift is first forced against the heel by the nail block, and thereafter upon the continued upward movement of the driver head, the plungers .15 are actuated to force the fastenings a, having thereon the washers I), through the heel and into .the sole of the shoe, the plungers being by such operation projected above the upper surface of the nail block a suflicient distance to embed the heads of the fastenings carrying the washers into the material of the top lift, as shown in Fig. 5. The nail block and driver head then descend, permitting the springs 17 to retract the plungers 15 into the nail block so that their heads 16 lie flush with the upper surface thereof, and the parts of the machine again assume the positions shown in Fig. 1, and are thereby in readibodied, but without limiting myself to this particular embodiment of the invention, nor to the details of construction described other than as defined in; the following claims, what I claim and desire to secure by Letters Patent of the United States is 1.
